Rather than send the entire INOV8 burner in for reconditioning, you can send the Module from the burner. That is the assembly that contains most of the small components and oil delivery that requires cleaning and possibly replacing. It looks like the photo and can be removed from the burner easily and within a few seconds, and can be packaged and sent to INOV8 for reconditioning. It will be thoroughly cleaned and tested and any failed components replaced. It can be upgraded with a digital temperature control if desired.
